Abrégé
(EN)

A plurality of methods, apparatus and computer program for providing a warning to a station (STA) associated with an Access Point (AP) in a WLAN indicating that a disassociation the AP is imminent. The steps of one of the methods include (a) selecting a station (STA) for disassociation from a particular Access Point (AP) of a WLAN; (b) updating a reason code field of a message(i.e. a measurement request frame or a site report response message) to indicate to the selected STA that it has become a candidate for disassociation; and (c) transmitting the message to the selected STA. Upon receipt by the STA of a message indicating that the selected STA has become a candidate for disassociation, the selected station scans other Access Points from a list to find another Access Point to associate with before being cut off by the current Access Point,and being finally handed off from the current to another (selected) Access Point.

WLAN에서 액세스 포인트(AP)와 결합된 스테이션(STA)에게 AP와의 분리가 임박했음을 나타내는 경고를 제공하는 다수의 방법, 장치 및 컴퓨터 프로그램이 제공된다. 이 방법 중 하나의 방법의 단계는, (a) WLAN의 특정 액세스 포인트(AP)로부터 분리되는 스테이션(STA)을 선택하는 단계와, (b) 메시지(즉, 측정 요청 프레임 또는 사이트 리포트 응답 메시지)의 이유 코드 필드를 갱신하여 분리용 후보가 된 선택된 스테이션을 나타내는 단계와, (c) 그 메시지를 선택된 스테이션으로 전송하는 단계를 포함한다. 선택된 STA가 분리용 후보가 되었음을 나타내는 메시지를 수신하면, 선택된 STA는 리스트로부터 다른 액세스 포인트를 스캔하여, 현재의 액세스 포인트에 의해서 컷오프 되어 결국 현재의 액세스 포인트로부터 다른 (선택된) 액세스 포인트로 핸드오프되기 전에 결합할 다른 액세스 포인트를 찾는다.
